Matlab standalone executable deployment- error using phantom function

Hey, I am working on matlab R2009A on ubuntu 11.04. Using the deploytool, I generated a test package for a matlab code of mine. Afterwards, I installed MCR using the command

sudo ./MCRInstaller.bin

which installed it at /opt/MATLAB/MATLAB_Compiler_Runtime/. Now to run the program, I extracted the package and then ran the file run_test.sh using command

./run_test.sh /opt/MATLAB/MATLAB_Compiler_Runtime/v710/ 10 128

where 10 and 128 are the arguments to the main function in the package. It gives me the error as

??? Error using ==> phantom>parse_inputs at 107

Unknown default phantom selected.

Error in ==> phantom at 69

Error in ==> MLEM at 3

Images:phantom:unknownPhantom

MLEM is my main program and at line 3, I have used the phantom function as

i = phantom(SIZE)

SIZE is an input argument(=128 in this case)

Hi Sabya,

just a guess: you know that input parameters to standalone applications are always passed as strings? This can be handled e.g. by

function myfunction(x,y)
if ischar(x)
  x = str2double(x);
end
if ischar(y)
  y = str2double(y);
end

Or using isdeployed instead of ischar ...

Ah! Great catch Titus!

[Sabya]

I put the following statements in my code

if(ischar(SIZE))

SIZE=str2int(SIZE);

end

Still no use, same error crops up.

[Titus Edelhofer]

Hi Sabya,

where does the str2int function come from? Or did you mean str2double? What I sometimes do in these cases: I add after the first line a

save c:\temp\inputVariables

so that all input variables are saved. Then run the compiled application. Then load in MATLAB the variables

load c:\temp\inputVariables

and call your MATLAB function with just these variables to see what happens ...

You cannot pass just a size to phantom(). The first parameter must be either a string or an array.

[Sabya]

No, thats not true. The function phantom works perfectly when run the code normally from matlab command line.

[Sabya]

I mean that the command

i=phantom(256)

work perfectly storing a 256x256 image in i

[Kaustubha Govind]

Does it work with 128 as the input argument when run in MATLAB? The error is coming from phantom>parse_inputs, and is not a standard MATLAB error, so it's hard to tell what could be going wrong without looking at your code. Perhaps putting some DISP statements in phantom>parse_inputs will help with debugging.

[Sabya]

the code woks fine when i execute it from matlab prompt as

MLEM(10,128)

[Walter Roberson]

Passing only a size to phantom is not a documented syntax in R2009a.

[Sabya]

I don't have the license associated with my account; so i can't view the above page. But the code is working in my system perfectly from matlab command prompt.

[Walter Roberson]

The R2009a documentation page is formatted differently than the current documentation page but contains the same information as the current (R2012a) documentation -- with no documented possibility of passing only a size.

If you insist on using undocumented behavior and your code fails, then we cannot be of assistance to you.

[Titus Edelhofer]

Hi Walter,

don't know about R2009a, but in R2012a the doc contains the following "example":

% ph = phantom(256);

% figure, imshow(ph)

Hello there, anyone would provide me an MLEM algorithm for image reconstruction? Thank you
